Centralised/Redirected profile information when working with Buddypress/multisite bbpress

Hello, Just hoping some wiser souls than myself can help clarify the following for me.

I have an administrative question with regard to buddypress, multi site and bbpress.

Intention is to have a multi site network comprising of 4 sites. I have buddy press installed on one but want members to use other functions on other sites such as

The Q and A -WPMUplug in

Forums/Topics -WPMU Plug in or BBpress

Question is can the profile information be centralised, redirected back to the Buddy press page or would i end up with several profile elements in different parts of the network?

Look forward to hearing from you guys.
